Gul Moonis, MD: Imaging of Otosclerosis
Otosclerosis is a slowly progressing disorder that affects the inner ear. It’s a leading cause of deafness in adults, usually appearing after the age of 40. It tends to be more common in women, specifically Caucasians. The disease may be hereditary in some individuals.
CT Scans are used in conductive, mixed or sensorineural hearing loss to help pinpoint a cause. In developed cases of hearing loss, imaging of otosclerosis is helpful in assisting professionals like Dr. Gul Moonis determine the type of otosclerosis and exclude contraindications for a cochlear implant.
There are two types of otosclerosis: fenestral and retro-fenestral. Fenestral presents as a lesion anterior to the oval window and can extend to the stapes. Retro-fenestral involves the cochlea. Most doctors prefer to use Multidetector CT imaging of the temporal bone. These scans, in the axial and coronal planes, help detect changes of otosclerosis.
